Aladdin has 12 gold coins in his magic bag. the genie tells him that for every 100 gold coins he has in his magic bag, he will get 25 extra gold coins every year. how many years later will aladdin have 21 gold coins in his bag?

There is not enough information to answer this question. He only has 12 in his bag so he wont be able to get the 25 coins

Step-by-step explanation:

7 years.

Step-by-step explanation:

We have been given that Aladdin has 12 gold coins in his magic bag. The Genie tells him that for every 100 gold coins he has in his magic bag, he will get 25 extra gold coins every year.

First of all, we will find increment rate of gold coins by finding 25 is what percent of 100 as:

The increase in coins in one year would be 25% of 12 that is coins.

Now we will use proportions to solve our problem as:

Therefore, 7 years Aladdin will have 21 gold coins in his bag.

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
